Nes won't stay on?

This is possible a problem with your A/V cords. Try "jiggling" them around when you have the NES turned on, and if there is no picture or sound after that, you may need a new set of the cables.

Search for the power supply model number NES-002. You can find several stores online that sell reproductions as well as several that sell used. A search of " nes-002 ac adapter" on Amazon returned several options.

Well it might be that the power deck has overloaded then.

72 pin game cart adaptor needs replacing. they can be purchased for around £10 and make it work like nes

The nes does this to stop people from playing pirated games, but it can also be because the game cartridge or console is dirty. Try cleaning inside the game cartridge with a cotton bud dipped in a cleaning product of some kind. it mostly works for me!

The FC Twin connects through an RCA connector, and can be hooked into a surround sound system. When using stereo and surround output from these systems, NES sounds and music may seem very different from their typical mono output. Using output modes that properly generate mono sound, either through a single center speaker or cloned to multiple speakers, the sound output sounds mostly identical to the original NES. The FC Twin does not produce some sounds faithfully, even with mono output; sound effects in the Super Mario Bros. series games will for example immediately seem different. Nevertheless, some later models of the console produce NES sound much more faithfully than units made closer to launch. Recent models produce sound with complete fidelity.

first off flip your nes upside down and remove the screws to the cover of nes..... then flip your nintendo over and remove the cover.... remember you just voided your warranty for your nes..... then proceed to do the following:

find Chip 3193A and find the 4th pin on the left hand side near the blue coils. Remove or pull back the pin and your NES Will play Pal and NTCS games.

okay there are three solutions the flashing is normal what it is
is that the connections are old and worn out so you can go buy a new 72 pin connector off ebay and search online alot of people have them and then you have to open your nes and replace it pretty cheap and easy but this will still flash once in a awhile

or you can buy a top loader there are alot on the market and they range in price as well
there is one that is made by nintendo but in good condition it is pretty price some times

and there are the aftermarket one which i have two and they are very well made and most play two systems i have one that play nes and snes and i have another that play nes and sega i bought both form ebay for around 40 -50 dollars each and they are very well made but they only accept the controllers that they are shipped with which is disappointing they look and have the same connection as snes or nes but nes or snes controller don't work and if you play alot and use stuff like game genie then the originals are the best to start with

i have a nes top loader and a original and two aftermarket toploaders as i used them all for differnet reason mostly some games are harder to get to work then others if you want to stay original then find the best one you can like one that some one bearly played then open it up your self or take it some where and have them clean it and replace the 72 pin connector with a new one and this should help greatly with the flashing also clean your games with some rubbing alcohol that some times help as the games are some times the probelm or you could have them professional cleaned up

what i do is any game or system i am planning on keeping is find the best one i can or a good price then i clean and replace all connections and clean all the games by opening them up then storing them in bags inside storage tote so they won't get nasty again and it seems to work but if you are starting with a system that is dirty and games that are pretty older then you relly have to play with it to get them to work and most of that time it's just better to pay alittle more for one that is in better condition i buy alot from garage sales and thift store that are in good condition just need a little touch here and there just look at the connections on the games the borad that the connections are on is white not brown or orange and the connections are gold not black and the system should have a clean looking inside don't worry about the connection as all older connections are bad just get a great looking system that functions turns on and off and the cartiage lockdown work and is smooth functioning the crack it open clean it up use alot of rubbing alcohol and compressing air and eletrionic cleaner and you should be good

to find the system look on ebay or search the internet try local game stores or try gamestop online

well i hope this helps thanks

It's a NES, after the light comes on the system works just got to try all the little tricks from back in the day of cartridge games.

the 1...2....3 push down trick

Sounds like the game is dirty, much like the original NES clean the game points, then try to clean the system points too.
